Abstract

The invention relates to a dyeing and finishing technology for silkworm silk fabrics. The steps comprises: firstly, a processing solution is prepared, ammonium hydroxide, an acetic acid solution and hydrogen peroxide are mixed fully, the pH value of the processing solution is adjusted to 3, the bath ratio is 1:30, and the temperature is risen to 25 DEG C; silkworm silk fabrics are placed in a water bath with a temperature of 25 DEG C and processed for 3-5min, then the temperature is risen to 60 DEG C, and processing is carried out for 30-40min; the silkworm silk fabrics are subjected to pre-setting and soft processing, then the processed silkworm silk fabrics are subjected to dyeing, namely, anhydrous sodium sulphate, an alkaline agent and dye are added at a room temperature, and fabrics after dyeing are obtained; then the fabrics are subjected to water washing and acid washing at a normal temperature, then are immerged into a soap washing solution, are washed for 10-20min and then are subjected to dye fixation, the dye fixation time is 20-30min, and finally setting is carried out on a setting machine. The dyeing and finishing technology is advantaged by environmentally friendly raw materials, simple operation, easy control and stable dyeing performances.

Description

technical field [0001] The invention relates to a dyeing and finishing process, in particular to a dyeing and finishing process of mulberry silk fabrics. Background technique [0002] Mulberry silk is a kind of natural fiber, which is a high-grade textile raw material. The fiber is thin and soft, and has good elongation, so it has high requirements for textile technology. favored by those. However, the traditional dyeing and finishing process of mulberry silk fabrics is usually too complicated, the process is long, time-consuming and energy-consuming, and causes serious environmental pollution. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a dyeing and finishing process of mulberry silk fabrics with environmental protection raw materials, simple operation, easy control and stable dyeing performance. [0004] For solving the problems referred to above, the technical scheme that the present invention adopts is:...
